1. An electrical DC to AC inverter having improved structure for providing improved thermal dissipation, comprising:

  • (a) a combination structural frame and primary heat diffuser of thermally conductive material, said frame having first and second opposed generally U-shaped cross-sections, said cross-sections being generally at right angles to each other and having a common base;

    (b) a cover over the said second U-shaped section, said cover being fastened to the frame and jointly defining with the frame an internal and enclosed electrical component compartment;

    (c) converting means mounted to the frame and within the component compartment for converting DC to AC, said converting means including a transformer mounted in direct heat exchange relationship to said common base;

    (d) means on the outside of the inverter frame for field wiring the inverter; and

    (e) secondary dissipation means mounted on an exterior surface of the frame for secondarily dissipating heat from the frame, said dissipation means being spaced from said field wiring means and being on a different side of the inverter.
